    You can either:
    - Go into the Device Manager on your PC, expand Network and click on the Atheros Wifi adaptor and use the Driver tab in the Properties to check for driver updates

    or if that doesn't update the driver

    - Visit your laptop manufacturer website and check for an updated Wifi driver.
